Security camera market is popular with new year and new weather

The application of intelligent security provides the most stable and harmonious protection for our community, enhances the soft power of the community and allows residents to live and work in peace and contentment. Economic development has accelerated the process of urbanization, and a large number of population has poured into cities, which has given rise to the development of urban communities. Smart security has kept pace with development, serving urban communities, providing visual management, and greatly improving community management functions. Real-time, vivid, and true reflection of monitored objects, with high reliability, easy implementation, and easy operation, gave birth to civil security market.

According to statistics, the coverage rate of civil security products in foreign countries has reached more than 70%. Its product features are elegant, safe, smart, simple and cost-effective. Although the domestic market is not yet mature, the huge market potential also holds great trading opportunities. With regard to the domestic market, China’s huge population base and household users, China’s civil security market can be expected in the next five years.

With the increasing popularity of civilian security and the rapid development of monitoring technologies, high-definition network cameras have become the main force of surveillance technology and have become one of the main directions of surveillance technology.

HD network cameras bring new changes together with optical imaging technology, intelligent analysis technology, network transmission technology, etc., while constantly satisfying the demands of market competition, they tend to be a perfect realization of self. High-definition network cameras have made new breakthroughs in technology over the past few years. They have profoundly affected the field of surveillance technology and will profoundly change our way of life.

Increased resolution

In terms of resolution, the development of high-definition network cameras can be said to be a byword. In addition to the current contact with more megapixels, 1.3 million pixels, 2 million pixels, 3 million pixels, 5 million pixels, 8 million pixels products are already The emergence of the market, even 10 million and more than 10 million pixel products have begun to show their clues in the monitoring industry. It can be said that people will never stop on the road to pursue more clearly.

COMS gradually replaced CCD

With the development of technology, the performance of CMOS sensors is rapidly improving. CMOS sensors respond faster than CCDs, and are therefore more suitable for high-volume data quality monitoring. From the market point of view, SONY, the traditional manufacturer of CCDs, has begun to shift its focus to CMOS sensors. In its production of high-definition network cameras, CMOS sensors have been adopted almost exclusively. This may be regarded as a CMOS sensor. Staged victory.

ISP (ImageSignalProcessing) is integrated by the encoding chip

By integrating ISP, not only can significantly reduce the system cost, but also greatly enhance the stability of the video, optimize the optical performance of the image. This has an important role to play in improving the imaging quality of high definition network cameras.

Intelligent analysis function is more practical

The intelligent analysis functions that have been implemented or are currently being implemented in high-definition web cameras include: video occlusion and video loss detection, video change detection, video blur detection, video motion detection, entrance and exit statistics, crowd movement, and congestion identification. Item identification, intrusion recognition, etc. These functions seem to be "less" than the previous smart analysis functions, but they are more practical. >>More

standardization

Whether it is ONVIF or PSIA, it is a standard formed by the spontaneous organization of enterprises, but from the perspective of getting more and more companies' response, it still has very important significance. In the next few years, standardization will become the passport for HD network cameras to reach the market.

Further improvement of transmission technology

At present, self-built optical fiber networks or local area networks are usually used to implement 1000M bandwidth networks in projects such as safe cities and financial network monitoring. This kind of Gigabit bandwidth resources, installed in the front-end 100 Road 1080P full-real-time high-definition network cameras (even if calculated by each channel occupying resources 4Mbps), occupying less than 50% of the total bandwidth resources; if you use 720P transmission, the bandwidth can also be reduced by half. In this way, it can fully support the practical application of high-definition network cameras.
